Escalation in the Strait of Hormuz: The War of Corridors and the Return of the Blockade

Summary

Despite the escalation, neither side appears to be seeking an all-out war, creating what may be described as a state of mutual strategic stalemate. The contours of this stalemate are clear: Iran cannot close the Strait for an extended period without harming its own interests, while the United States cannot forcibly reopen it without incurring significant risks. Both sides possess tools for escalation, yet neither has a clear path to victory. The result is a state of fragile stability in which tensions persist without developing into a full-scale confrontation.

Throughout 2026, the Gulf region witnessed a qualitative escalation that redefined the nature of the conflict between Iran and the United States—not only in terms of the instruments employed, but also in terms of the geopolitical arena itself. The Strait of Hormuz is no longer merely a maritime chokepoint or a temporary instrument of pressure; rather, it has become a center of gravity within a broader network of strategic corridors extending from the Gulf to Eurasia.

In this context, Iran is attempting to promote the idea that its behavior has undergone a clear shift from a policy of “strategic patience” to a model of “active deterrence,” while the United States faces a predicament characterized by diminishing options and the rising cost of achieving a decisive outcome.

This article seeks to analyze the latest escalation on three levels: first, Iran’s attempt to redefine the Strait of Hormuz as an instrument over which it seeks to assert sovereign authority; second, the expansion of the conflict into what may be termed a “war of corridors”; and third, the state of mutual strategic stalemate between Tehran and Washington.

Iran is seeking to highlight the end of strategic patience and the beginning of active deterrence, with the aim of restoring its instruments of influence—or exploiting the latest escalation to acquire new sources of leverage that compensate for the losses it and its proxies have suffered over the years.

For years, Iran pursued a policy of “strategic patience,” based on absorbing pressure and avoiding direct confrontation while preserving latent deterrence capabilities. Developments in 2026, however, revealed a clear shift toward a more assertive strategy and a more explicit use of force.

This shift is reflected in three main indicators:

Redefining the Rules of Engagement

Iran is no longer content with limited or indirect responses. Instead, it has begun seeking to impose new rules of engagement based on the principle that any threat will be met with a direct or indirect response extending beyond the traditional framework.

This is particularly significant given that the war was brought onto Iranian territory. Tehran was unable to avoid direct warfare as it had sought to do in the past by keeping military confrontations beyond its own borders and shifting battlefields into neighboring countries.

The Politicization of Geography

The Strait of Hormuz has shifted from being viewed merely as an international waterway to becoming an instrument that Iran seeks to frame in terms of sovereign authority and use to reshape regional balances.

Rather than accepting the principle of “freedom of navigation,” Tehran has begun promoting the concept of “sovereign management of strategic corridors,” which would allow it to influence the terms under which vessels pass through the Strait.

Although Iran continued throughout the war to speak of coordination with Oman regarding passage through the Strait, it simultaneously sought to disregard the Sultanate’s sovereign rights over its territorial waters. Iran attacked vessels that used the southern route designated by Oman and declared that it would accept only passage through the route closer to Iranian waters, in an attempt to establish unilateral control over navigation and maritime traffic through the Strait while overlooking Oman’s sovereign rights.

Expanding the Scope of Deterrence

Iran’s response is no longer confined to the Gulf. It has expanded to include infrastructure and strategic sites across the region, reflecting a shift from tactical deterrence toward a multidimensional model of regional deterrence.

Second: The “War of Corridors”

One of the most significant transformations in the current escalation is its evolution from a conflict centered on a maritime strait into a broader struggle over strategic corridors.

This transformation can be described through the concept of a “war of corridors,” in which transportation, trade, and energy routes themselves become major arenas of geopolitical competition and conflict.

Corridors as Instruments of Power and Conflict

In a world increasingly dependent on supply chains, control over the flows of goods, energy, and transportation has become a decisive source of power.

The United States is therefore seeking to reduce dependence on the Strait of Hormuz by developing alternative routes, whether maritime or overland. Iran, by contrast, views any viable alternative route as a direct threat to its geopolitical position and to an important strategic source of leverage it has acquired through the war. Tehran therefore seeks either to obstruct such alternatives or bring them within its sphere of influence.

The recent period has witnessed an escalation in attacks targeting infrastructure associated with strategic corridors, including bridges, railways, and transregional transportation networks. The objective is not merely to inflict physical damage, but also to undermine potential overland alternatives and transportation corridors that Iran could use to circumvent the maritime blockade imposed by Trump.

At the same time, Iran constitutes an important link in the International North–South Transport Corridor, and any weakening of its position could affect broader projects connected to global trade.

The conflict is therefore evolving from a regional confrontation into part of a wider global competition over the reshaping of economic geography. This helps explain U.S. attacks on infrastructure and bridges in northern and northwestern Iran, as well as operations along Iran’s southern and western borders aimed at weakening its control over the Strait of Hormuz.
